From b75d8dc5642b71eb029e7cd38031a32029e736cc Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 26 Jun 2020 15:13:33 +0900 Subject: treewide: convert bd_t to struct bd_info by coccinelle The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include #include void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: @@ typedef bd_t; @@ -bd_t +struct bd_info Signed-off-by: Masahiro Yamada --- post/drivers/memory.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'post') diff --git a/post/drivers/memory.c b/post/drivers/memory.c index 9cc48b1..e90ada3 100644 --- a/post/drivers/memory.c +++ b/post/drivers/memory.c @@ -470,7 +470,7 @@ static int memory_post_tests(unsigned long start, unsigned long size) __attribute__((weak)) int arch_memory_test_prepare(u32 *vstart, u32 *size, phys_addr_t *phys_offset) { - bd_t *bd = gd->bd; + struct bd_info *bd = gd->bd; *vstart = CONFIG_SYS_SDRAM_BASE; *size = (gd->ram_size >= 256 << 20 ? -- cgit v1.1
